When I saw Canoga Park in part of the description mentioned I was interested to say the least. I lived maybe a half a block from the little cut off SP had, where dirt Canoga Ave ended right next to paved Canoga Ave?. It met back up with the Coast Line below Lassen Ave. Spent a lot time walking(hanging out)around that section of track from the 3rd grade to my late teens, this was back in the 70's-80's. I thought it would be cool for a small route to do from Chatsworth Park towards East Reseda maybe Van Nuys. It's one reason if I had the extra dollars to get TransDem(That and SP's Soledad Canyon Line). Anyways Good Luck and keep up the good work!

P.S. Not that it matters and I've probably killed another thread, but I was up at the Chatsworth station(platform) when Amtrak first started replacing the F40's in that area with the P32's and the first day Metrolink ran there(Christ I'm getting old) to take photo's.
